Now, though, he's stepping down from directly overseeing the Apple account and relinquishing his post as chief creative officer of the Media Arts Lab, according to AdAge. (He'll stay on as chairman and global director of Media Arts Lab and as chief creative of the TBWA network, according to the same report.)

Clow is also known for his work on the Energizer Bunny and the Taco Bell Chihuahua, but apparently never saw fit to attach a cuddly animal to Apple's brand—like the Macintosh Muskrat or, and we're just spitballing here, a half man, half antelope, half Mac.

Taking over for Clow is Duncan Milner, who's served as executive creative director on the Apple account since 1990, and has also worked on Nissan, Levi's, and Pedigree.

Update: In a reputed memo to staffers, Clow clarified that Milner's promotion was meant to reward the "great job he's been doing leading the Media Arts Lab," and that the focus should be on Milner's success, and not Clow's evolving role. Clow added further that he's working "every day, meddling in everything that goes on, pushing the creative on many brands including keeping an eye on Apple."
